Comparison of IC50 values for Org 27569 and PSNCBAM-1 as inhibitors of CP55940, WIN55212, and anandamide in the β-arrestin assay performed with hCB1 cells. Columns represent mean values ±S.E.M. from three to four experiments carried out in duplicate. The IC50 values (nM) were obtained using Prism 5 to construct concentration-response curves of the inhibitor concentration versus the percentage reduction in each agonist Emax value.
